setVirtualMainVolume does not work with scope: .input

[michaelphagen]

The setVirtualMainVolume function fails when trying to set the input volume of a device (Avid HDX Interface) using scope: .input on MacOS Big Sur 11.6.1.

The function works properly when using the .output scope.

I do not have other interfaces available to test, however, I can set the input volume using .setVolume(1.0, channel: 0, scope: .input), so I am using that as a workaround.
